Starting with the results:
Scores are out of 9 possible points from 9 categories, including: Display, Battery, Build & Design, Audio, SoC/System Performance, Options, Software, Security and Camera. Each category has sub categories which add up to one possible point each.
Here are the results by category:
Sub Categories and Definitions:
Display
Accuracy - Display Color Accuracy as measured by Anandtech
Brightness - Max brightness as measured by Anandtech
Quality - Takes into account screen power consumption and viewing angles
Resolution - Max resolution of the device (most of the time measuring QHD vs FHD)
Battery
Size - Battery Size
Life - Battery Life
Charging Speed - Self Explanatory
Charging Tech - Highest marks for properly implemented USB C, lowest marks for broken or proprietary implementations
Build & Design
Navigation Buttons - Highest marks for onscreen buttons, lowest marks for off-screen physical buttons (as opposed to capacitive or hybrid)
System Buttons - Accounts for location and quality of volume up/down and power buttons
Build Quality - Fit and finish – how well the device is put together, including durability considerations
Build Materials- In this ranking Metal > Glass > Plastic
Layout - Device layout, includin reachablility of components and the phone face design
Screen Size - Measures distance from 5.5” – considered by a quick survey to be the best phone size
Audio
Speaker Location - Highest marks for two stereo speakers on the front of the device, lowest marks for a speaker on the back of the device
Speaker Quality - How good the speakers on the phone sound
DAC & Amp - Added technology to make headphone listening experience better
Performance
GPU - Quality of GPU performance on SoC
CPU - Quality of CPU performance on SoC
Base Storage - Lowest Storage Option Available
Max Storage - Highest Storage Option Available
RAM - Base RAM quantity – if more than one version of phone, lowest is marked here (for example, a phone where the 64GB version comes with an extra GB of RAM).
Options
Colors - Volume of color options, highest marks for 3 or more color options
Storage Size - Highest marks for more storage options, lowest for only having one version available – No points are added for having removable storage unless Google’s Adoptable Storage is implemented
Carrier Choice - Availability on all major networks in the US – preference given to one device SKU that covers all four
Software
Resist Obsolecence - Highest software version as of today compared to highest software version predicted for EOL
Timely Updates - OEM track record for speed of firmware updates and security updates
Design - UI and OEM added app designs
Lack of Bloatware - Self Explanitory
Security
FPS - Quality of Fingerprint Scanner
Software - Security Software (level of encryption, highest security update)
Camera
DXOMark - Score on DXOMark
Options - Availability of sought-after features, such as manual controls, etc.
Consistency - Reliability of camera to get a decent or good shot every time, rather than just being capable of getting a good shot in certain conditions
Speed - Speed of camera, shutter and cycle.
